Description

Embedded ceiling light fixture with heat dissipation space

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded ceiling lamp mounted on a ceiling with a heat dissipation space, in particular, a bracket device is disposed on the outer periphery of the lamp, and is fastened by a buckle device to fit the outer surface of the lamp. And a spring is disposed in the bracket device to enable the bracket device to have a movable stroke. When the lamp is installed in the ceiling, the buckle device is touched and squeezed, thereby disengaging the bracket device from the bracket device, according to The resilient force of the spring causes the bracket device to expand outwardly into a fixed bracket to form a heat dissipating space around the luminaire. Background technique

The embedded ceiling lamp is installed in the ceiling, which has good concealment and illuminating effect, and in order to make the building have thermal insulation, energy saving and environmental protection effects, people adopt insulation materials on the ceiling, although the quality is light and It has good thermal insulation function, but it definitely increases the sealing of the space inside the ceiling, and makes the lamps installed in it not be able to effectively dissipate heat, directly causing the temperature rise too high; light will seriously affect the luminous efficiency and life of the bulb. For example, energy-saving lamps and LED lamps, more serious, may damage the ceiling, and even cause fires, such as embedded ceiling lamps with halogen bulbs. The temperature of the lamps and ceilings often exceeds that of the United Kingdom and other countries. The standard of 90 degrees Celsius specified in the temperature rise test of the luminaire is considered to be a fire hazard. Therefore, in order to alleviate the phenomenon that the temperature rises too high during illumination, a variety of heat-dissipating ceiling lamps have appeared on the market, including a heat-dissipating lamp with a small electric fan installed in the lamp, and a fan is used to drive the lamp around the lamp. The air flows and dissipates heat into the air. However, the disadvantage of installing the fan is that it generates noise, is prone to failure and increases production cost, and is not suitable for use in a quiet environment, which is easy to cause, and requires more wiring and expansion. The complexity of the installation of the luminaire.

However, if a predetermined space is left around the lamp, the heat emitted by the lamp can be diverged outward, effectively reducing the temperature rise of the lamp. Currently, the space for the lamp is reserved mainly before laying the insulation material. First, a fire-proof cap is placed on the upper part of the lamp to avoid the sealing state formed by completely filling the insulating material around the lamp. The fire-proof cap is mainly composed of a frame, and the surface of the bracket is impregnated with liquid. The glass fiber cloth of the expanded material forms a space, which is generally called a fireproof cap, and the glass fiber cloth has a fireproof and breathable effect, and once it is heated up, it also has a function of impervious to smoke, but it is expensive, installation cost High, so there is also a tin box made of steel material, and the iron box is used to provide a heat dissipation space for the lamp to reduce the installation cost, but whether it is a fireproof cap or the iron box, There is a common shortcoming, that is, the installation steps are very cumbersome, especially the installation order, and the ceiling must be installed. After work simultaneously, followed by the installation position to accurately arrange good lighting, and then install the ceiling, once installed ceiling without installing these fire hat or tin, then it is difficult to place it in the inside. Therefore, for the decoration worker or the consumer, it is desirable to have an embedded ceiling lamp that avoids high cost and cumbersome installation steps, and at the same time has a simple installation method, which can meet the quick installation and can be given Products with sufficient heat dissipation space are born to reduce the complex problems caused by installing lamps. Summary of the invention

In order to solve the above problems, the present invention is an embedded ceiling lamp with a heat dissipation space, and the main purpose thereof is that when the ceiling lamp is mounted on the ceiling, it is as simple and convenient as installing a traditional ceiling lamp, and, for a ceiling lamp, There is enough space for heat dissipation around the ceiling to solve the problem that the ceiling is sealed by fireproof cotton or insulating material.
